i drove over 700 miles today. about 20 miles before i got home, there was a most unpleasant noise from my front end, then chunks of stuff started flying out behind my truck and it swerved back and forth. i eased it off the road and into a gas station. (i had been going 80) the right front tire was leaning in about 3 inches. got towed, will get rental. i'm just glad it didn't happen in the middle of nowhere.
